'The oscillating valves F and F are mounted on shafts lc and lc', which nre arranged across the steam-chest and water-hex,respectively, and have their bearings in the s zrmc. These shofts lc 7c are provided with cranksoutside of their respective boxes, as vis iiulicntedl by dotted lines in ig. 1 The endsl ofthese cranks `are connectedl by horizontal ban-sl Zwith the upper end ofn lever, m, which is pivotetl hy a. pin, n, toa stationery arm, o, projecting from the frame C. The lower end of the lever m-is provided with a pin or friction-roller, which lits into the groove in thcdisk P. As long' as this pin is Vin the concentricportioi of the groove, the lever m, bars Z, shafts c k', ondvalves F F will remain stationary in o, certain position while n stroke is being made by the pistons. As soon es the pin on the lever com'es into' the eccentric portion of the 'f groovein the dislc P, the leverfm und its appendages willv be moved ond the valves shifted, so as to change the Thenoperation is-simple, and-as follows: When the valve F stands as shown in ig. 1,' the steam will enter thecylinder H through the port b, driving the'pistons in -the direction of the arrow 1, fig. 1. The water will .then beforced through the port lf into the wouter-box anden-chamber, while vu-ter will be drawn into the port andthe space between'the heed Bffmd piston G will beilled with it. `When the stroke of thepistons has .been r'nishe'dY the valves will be shifted so :is-te open the Vpassage b to the stoner-chest and the ,port a to the wate'r-box. The pistonswill then he moved inthe opposi'todirection, but thqsame reslt willbe obtained.
